The Three Collision Stages

The Three Collision Stages


When a collision happens, it’s important to know what is happening to both you and your vehicle. That’s why our team at Collision 24 has compiled this review of the three collision stages.

Learn about each stage and how we can help you get back on the roads around Brockton, Randolph, and Stoughton, Massachusetts.

First Collision: Vehicle Collision

First Collision: Vehicle Collision

The first stage is known as a vehicle collision. This occurs when the vehicle strikes another object and is most closely associated with a car crash.

As the car collides with another object, it begins to crumple and slow down. The ability of the vehicle to crumple is important, as it takes away some of the energy of the crash, thus helping to protect the people inside. That’s why specific crumple zones are intentionally designed for every automobile.

An entire vehicle collision—from the initial contact with another object to a full stop—occurs quickly. For instance, a vehicle traveling at 30 MPH will experience the entire process in about one-tenth of a second.

While that isn’t a whole lot of time to react, there are some things you can do to lessen both the impact of the crash and personal injury. If you’re ever experiencing a situation with an oncoming collision, try to veer into an object that can absorb some of the energy, like a bush.

It’s important to remember, though, that while this is taking place, the two other stages of a collision are just beginning.

Second Collision: Human Collision

When the vehicle begins to crumple and slow down, its occupants are still moving at their normal speed and direction. This continues until the occupants come in contact with an object that causes their forward motion to stop.

It is during this second stage that we see the importance of properly equipped seatbelts and airbags. Think of a moment when you had to step on the brakes quickly; you may have been jerked forward ever so slightly, but thanks to your seatbelt, your body was prevented from going any farther.

Third Collision: Internal Collision

Third Collision: Internal Collision

As the vehicle and its occupants slow down, the organs and body tissues inside each person are initially still moving toward the point of impact. Just as in the second collision, their inertia continues to move them even as the body surrounding them begins to slow down. 

This makes proper restraint within a vehicle vital, as it might be key in helping reduce internal injuries.

How to Reduce the Risk of Injury During a Collision

Now that you’re familiar with the three stages of collisions, here are some helpful ways you can lessen the risk of serious injury. Let’s take a look.

  • Maintain Correct Seat Position: A seat that’s not positioned correctly could cause whiplash along with leg, back, and neck injuries. Your seat should always be positioned close enough to the pedals so your leg is not fully extended. In the event of a crash, bent legs help reduce harm to the lower back.
  • Secure Loose Items: Having your belongings safely inside the trunk and other compartments available inside the car can help avoid injuries caused by flying objects during a collision. Loose items can become dangerous projectiles, so it’s important to keep everything secured.
  • Keep Children in Car Seats: The proper car seat is crucial in keeping your children and toddlers safe in the event of an accident. You’ll want to make sure you’re using the proper seat for your child’s age. Furthermore, any child under 13 years of age should always sit in the rear seat of your vehicle.

These preventive measures can significantly reduce the risk of injury during a collision. By taking these steps, you enhance the safety of everyone in the vehicle, ensuring a more secure driving experience.
